Change Background Color on 404 Page

Is it possible to change the background color of the default 404 Page?

I would like to either use a custom color, or an image.

Thank you!

Hello Christopher,

As klmbr mentioned above, you can change this with CSS:

.error-holder {
background-color: #333;
}
And really a good suggestion about “right click on the element and inspect.” which will help you customize a lot of design without waiting for us to help.

Thank you
